ABSTRACT:
A folding structure useful as a "climber" or climbing type play equipment for children can be constructed so as to utilize an odd number of sides located in side edge to side edge relation. One of the sides used can be referred to as an end side; the remainder of the sides consist of an even number of pairs of sides, the sides on each of the pairs having identical external dimensions. Hinges are utilized to connect the adjacent edges of all of the sides to one another so as to form a continuous "band" type structure. The sides are of such external dimensions as to permit them to be folded between an open position in which all of the sides define a hollow structure and a collapsed position in which the sides of the pairs of sides extend adjacent to one another in a stacked relationship and in which the end side extends along side edges of the sides as they are located in this stacked configuration.
